ABSTRACT

A dermal papilla cell growth promoter, a hair growth stimulant and a hair growth tonic containing a compound having an activity of inhibiting the function of WNT-5A.

TECHNICAL FIELD

The present invention relates to a dermal papilla cell growth promoter, a hair growth stimulant and a hair growth tonic. More specifically, it relates to a dermal papilla cell growth promoter, a hair growth stimulant and a hair growth tonic comprising a WNT-5A function inhibitor as an active ingredient. Furthermore, the present invention relates to a method of screening a dermal papilla cell growth promoter based on the effect of inhibiting the function of WNT-5A.

BACKGROUND ART

Human hair follicles are made up of epithelial and mesenchymal dermal cells such as keratinocytes, dermal papilla cells, fibroblasts and sebaceous cells and hair growth cycle (hair cycle) is controlled via interactions among these cells. The hair shaft is formed by the proliferation/differentiation (keratinization) of follicular keratinocytes. Dermal papillae regulate the proliferation, differentiation and apoptosis of these follicular keratinocytes and thus play a key role in the control of the hair cycle. In developing a hair growth stimulant/a hair growth tonic, therefore, it would be important to study effects on dermal papilla cells. However, molecular mechanisms regulating the proliferating ability and hair-cycle controlling ability of dermal papilla cells have been scarcely clarified so far.

On the other hand, WNT-5A is a secretor glycoprotein belonging to the WNT family. The WNT family includes about 20 kinds of molecules which are conserved over a wide range from nematodes to mammals. It is known that these WNTs are important intercellular signaling molecules which regulate axis formation and organ formation during the fetal stage (Annu. Rev. Cell Dev. Biol, 14, 59-88 (1998); Genes & Dev. 11, 3286-3305 (1997)). In humans, there are 10 kinds of WNT receptors that are Frizzled seven-pass transmembrane receptors (Annu. Rev. Cell Dev. Biol., 14, 59-88 (1998), Genes & Dev., 11, 3286-3305 (1997)). Depending on WNT-Frizzled bond combinations, there exist 3 kinds of signal transduction pathways (i.e., WNT/β-catenin pathway, PCP pathway and WNT/Ca²⁺ pathway) (Annu. Rev. Cell Dev. Biol., 14, 59-88 (1998)).

In recent years, it is clarified that the WNT/β-catenin pathway is fundamental to the formation of hair follicles (Genes & Dev., 8, 2691-2703 (1994); Cell, 95, 605-614 (1998), Dev. Biol., 207, 133-149 (1999); Genes & Dev., 14, 1181-1185 (2000); Cell, 105, 533-545 (2001)). In 1988, a stabilized β-catenin transgenic mouse in the skin was constricted. It is reported that this mouse showed increased de novo follicular morphogenesis and led to hypertrichosis (Cell, 95, 605-614 (1998)). It was reported in 2000 that the WNT/β-catenin signal plays an important role in maintaining the hair-inducing activity of dermal papilla (Genes & Dev., 14, 1181-1185 (2000)).

However, it has been clarified that signal transduction from WNT-5A is mediated not by the WNT/β-catenin pathway but by the Ca²⁺ pathway (Dev. Biol., 182, 114-120 (1997); Curr. Biol., 9, 695-698 (1999)) and nothing has been reported so far with respect to the relationship between WNT-5A and follicle morphogenesis.

It is furthermore reported that duplication of the embryonic axis is induced by injecting Xenopus laevis WNT-5A mRNA together with human Frizzled 5 mRNA into an early of Xenopus laevis embryo (Science, 275, 1652-1654 (1997)) while the axis duplication induced by the injection of WNT-1 or WNT-8 mRNA is inhibited by WNT-5A (J. Cell Biol., 133, 1123-1137 (1996)), and that Xenopus laevis WNT-5A binds to rat Frizzled 2 and activates CamKII (Ca²⁺/calmodulin-dependent protein kinase II) and PKC (protein kinase II) via the Ca²⁺ pathway (Curr. Biol., 9, 695-698 (1999)). However, physiological meanings thereof still remain unknown and nothing has been reported so far with respect to the relationship between WNT-5A and hair growth stimulation/hair growth promotion.

Based on the above-described morphological characteristics and culture properties, the characteristics of this strain are compared with various known species reported in (1) K. H. Domsch et al., Compendium of soil fungi, Vol. 1, IHW-Verlag (1980) and (2) G. L. Barron, The Genera of Hyphoomycetes from soil, Williams & Wilkins (1968) and the like. As a result, this strain is closely similar to an incomplete species known under a classification name Verticillium chlamydosporia or Diheterospora chlamydosporia and, therefore, seemingly belongs to the same species. In (3) R. Zare, W. Gain and H. C. Evans, A revision of Verticillium section Prostrata. V. The genus Pochonia, with notes on Rotiferophthora, 73, 1-2, p 51-86 (2001), this species is molecular systematically re-examined and, in its turn, referred to as belonging to the genus Pochonia as the proper genus. Moreover, it is suggested to refer such a species forming non-linked Verticillium-type conidia as the strain of the present invention as to a variant Pochonia chlamydosporia var. chlamydosporia.

Based on these facts, this strain is named “Pochonia chlamydosporia var. chlamydosporia TF-0480”.

Dermal Papilla Cell Growth Promoter

The term “dermal papilla cell growth promoter” as used in the present invention means a medicament or a reagent having an effect of increasing the number of dermal papilla cells.

The dermal papilla cell growth promoter according to the present invention is characterized by being based on the effect of inhibiting the function of WNT-5A. Since WNT-5A inhibits the functions of WNT-1 class molecules (WNT-1, WNT-8, etc.) which are activators of WNT/β-catenin pathway, the growth of dermal papilla cells is controlled by regulating the function of WNT-5A or regulating the expression of WNT-5A. Therefore, even compounds having completely different structures (e.g., Compound 24, Compound 79, Compound 7, etc.) have an excellent effect of promoting the growth of dermal papilla cells, so long as these compounds have an excellent effect of inhibiting the function of WNT-5A.

The growth of cells can be measured by a method publicly known by a person skilled in the art. Examples of the measuring method include counting of viable cells using an appropriate color-developing substrate and the [³H]-thymidine uptake method. As the color-developing substrate, tetrazolium salts such as MTT, MTS and XTT and Alamar Blue are preferably used.

Hair Growth Stimulant/Hair Growth Tonic

The term “hair growth stimulant or hair growth tonic” as used in the present invention means products to be used for inducing hair growth, promoting hair growth, preventing alopecia and the like. In the case of using the hair growth stimulant and hair growth tonic according to the present invention as medicaments, the subject to be applied includes improvement or prevention of alopecia areata and male pattern alopecia.

The effects of the hair growth stimulant and hair growth tonic according to the present invention are achieved by the effect of promoting the growth of dermal papilla cells by inhibiting the function of WNT-5A. Based on this function mechanism, the cell growing ability, which has been depressed in dermal papillae in an alopecia site, is enhanced and dermal well-developed papilla tissue is formed. It is therefore expected that the hair growth stimulant/hair growth tonic according to the present invention are efficacious against symptoms on which little effects can be established by the existing hair growth stimulants and hair growth tonics.

It is furthermore expected that synergistic effects could be obtained by combining the hair growth stimulant and hair growth tonic according to the present invention with other hair growth stimulants and hair growth tonics having different function points.

The hair growth stimulant and hair growth tonic according to the present invention can be administered in various doses and various dosage forms depending on individual compounds.

In the case of administering the compound represented by formula (IX) by application (lotion, ointment, a gel, etc.), for example, it can be administered at a dose of 0.0001 to 10% by weight, preferably 0.001 to 5% by weight and more preferably 0.001 to 1% by weight, although the dose varies depending on the type and dosage form of the hair growth tonic. In the case of orally administering (dust, tablet or capsule) the compound represented by formula (IX) to a male adult, the daily dose preferably ranges from 1 to 100 mg/kg.

Although the dosage forms of the hair growth stimulant and hair growth tonic according to the present invention are not particularly restricted, it is preferable to provide the hair growth stimulant/hair growth tonic containing a WNT-5A production inhibitor (e.g., the compound represented by formula (IX)) as an active ingredient in the form of a water-soluble composition in the case of external application. Such a water-soluble composition can be produced by using various additives (humectant, thickener, preservative, antioxidant, aromatic coloring agent, etc.) commonly employed in producing drugs, quasi drugs or cosmetics, so long as the effects of the present invention are not damaged thereby. The hair growth stimulant and hair growth tonic according to the present invention can be provided as hair-care compositions such as hair tonic, hair oil, hair moose or gel, or ointments.

In the case of using hair growth stimulant and hair growth tonic according to the present invention as liquid preparations, such a preparation is produced as an aqueous solution, a non-aqueous solution, a suspension, liposomes or an emulsion prepared by dissolving a WNT-5A production inhibitor (e.g., the compound represented by formula (IX)) in purified water, an appropriate buffer such as a phosphate buffer, a physiological salt solution such as physiological saline, Ringer solution or Locke solution, ethanol or glycerol appropriately combined with a surfactant, etc. commonly employed, followed by sterilization. It is topically administered as a liquid preparation for scalp. The liquid preparation may be applied directly to the scalp. Alternatively, it may be applied by using a jetting nozzle such as a spray.

In the case of using hair growth stimulant and hair growth tonic according to the present invention as semi-solid preparations, a WNT-5A production inhibitor (for example, the compound represented by formula (IX)) is mixed with a fat, an oil, lanolin, vaseline, paraffin, wax, a plaster, a resin, plastic, glycerine, higher alcohol, glycerol, water, an emulsifier, a suspending agent or the like to give an external preparation (ointment, cream, etc.) which can be topically administered.

In the case of using hair growth stimulant and hair growth tonic according to the present invention as solid preparations, a WNT-5A production inhibitor (e.g., the compound represented by formula (IX)) is mixed with appropriate additive(s) to give an external preparation such as a dust or a powder. Alternatively, it is possible to produce a solid preparation which is dissolved or suspended in a solvent before using and applied to the scalp.

In the case of orally using, it is preferable that a WNT-5A production inhibitor (e.g., the compound represented by formula (IX)) is blended with a pharmaceutically acceptable carrier (filler, binder, disintegrating agent, flavor, corrigent, emulsifier, etc.), a diluent, a dissolution aid or the like and the obtained medicinal composition is processed in a conventional manner to give a tablet, a capsule, granules, a dust, a syrup, a suspension, a solution and the like.

These preparations can be produced by using formulation techniques commonly employed.

Screening Method

The present invention further relates to a method of screening a dermal papilla cell growth promoter, which comprises selecting a compound inhibiting the function of WNT-5A.

Selecting a compound inhibiting the function of WNT-5A (hereinafter sometimes referred to as “WNT-5A function inhibitor”) means, for example, selecting (i.e., screening) a WNT-5A production inhibitor, or selecting a WNT-5A receptor antagonist.

As test materials to be subjected to the screening method according to the present invention, any materials can be used. That is, the test materials are not restricted in kind, and they may be low-molecular weight compounds, compounds contained in a natural extract or synthetic peptides. They may also be a compound library or a combinatorial library. The compound library can be constructed by a method publicly known by one of the skilled in the art. Alternatively, a commercially available compound library can be used. From the viewpoint of using as a medicament, the compound which is subjected to screening preferably has a molecular weight of 3000 or less. From the viewpoint of enabling application/oral administration, a low-molecular weight compound having a molecular weight of 600 or less is preferred.

(1) Method of Screening WNT-5A Receptor Antagonist

In a method of screening a WNT-5A receptor antagonist, whether or not a bond between the WNT-5A protein and the WNT-5A receptor is formed can be examined by using a labeled WNT-5A protein and a WNT-5A receptor and detecting or measuring the label. Examples of the label include a radioisotope (³²P, ³³P, ¹³¹I, ¹²⁵I, ³H, ¹⁴C, ³⁵S, etc.), an enzyme (alkali phosphatase, hoarse radish peroxidase, etc.), a fluorescent substance (fluorescein isothiocyanate, etc.) and the like. They can be commercially available and the labeling can be made by a known method.

A specific example of an in vitro assay system is performed in a cell-free system. More specifically, one of the WNT-5A protein and the WNT-5A receptor is bound to a support and the other and a test material are added thereto. After incubating, the reaction mixture is washed and the binding of the other protein to the protein having been bound to the support is detected or measured.

Examples of the support to which the protein is bound include insoluble polysaccharides such as agarose, dextran and cellulose; synthetic resins such as polystyrene, polyacrylamide and silicone; and the like. More specifically, commercially available beads and plates obtained by these materials can be employed.

(2) Method of Screening Compound Inhibiting WNT-5A Production

A compound inhibiting WNT-5A production can be screened by using the amount of WNT-5A mRNA or the amount of WNT-5A protein as an index. It is also possible to bind a reporter gene to the promoter region of a WNT-5A gene and detect the expression amount. As the promoter of the WNT-5A gene, one represented by SEQ ID NO:3 is preferably used.

Examples of the reporter gene include a GFP green fluorescent protein) gene, a GUS (β-glucuronidase) gene, an LUC (luciferase) gene, and a CAT (chloramphenicol acetyltransferase) gene.

When the expression amount of WNT-5A mRNA is used as an index, for example, human WNT-5-expressing cells are used and a test material is added thereto. After culturing in an incubator for several hours at 37° C. in a 5% CO₂-95% air atmosphere, the cells are lysed and RNAs are extracted. Then, the amount of the WNT-5A RNA is measured by, for example, RT-PCR. Thus, a material having an activity of decreasing the WNT-5mRNA amount can be searched. The primers used in PCR are not particularly limited, so long as they are specific to WNT-5A mRNA, and they can be designed from the WNT-5A mRNA sequence. Preferred examples include a forward primer AATGTCTTCC AAGTTCTTCC TAGTGGC (SEQ ID NO:8) and a reverse primer GATGTCGGAA TTGATACTGG CA (SQ ID NO:9).

When the WNT-5A protein amount is used as an index, for example, human WNT-5A-expressing cells are used and a test material is added thereto. After culturing in an incubator for several hours at 37° C. in a 5% CO₂-95% air atmosphere, the cells are lysed by using the culture medium and proteins are extracted. Then, the amount of the WNT-5A protein is measured by ELISA (enzyme-linked immunosorbent assay) or the like. Thus, a substance having an activity of decreasing the expression amount of the WNT-5A mRNA can be searched.

Next, the present invention is described in detail by reference to Test Examples below, however, the present invention is not limited thereto.

TEST EXAMPLE 1

Expression of WNT-5A mRNA in Dermal Papilla Cells:

Human dermal papilla cells, which were purchased from Toyobo, were cultured in MEM (Invitrogen) containing 12% FBS. Human hair follicle cells were separated from plucked hairs in accordance with the method of Arase et al. (J. Dermatol. Sci., 2, 66-70 (1991)) and cultured by using KGM-2 (Sanko Junyaku).

The dermal papilla cells in passage 5 and the hair follicle cells in passage 2 were sowed in a 10 cm dish to give a density of 2×10⁶ cells/well and cultured over 2 nights. After removing the medium, the cells were washed with PBS(−) and total RNAs were extracted by using TRIzol reagent (Invitrogen). Using 50 ng of the total RNAs, 0.4 μM primers specific to WNT-5A or glyceraldehyde3-phosphate dehydrogenase (GAPDH) [NT-5A forward: AATGTCTTCC AAGTTCTTCC TAGTGGC (SEQ ID NO:8), WNT-5A reverse: GATGTCGGAA TTGATACTGG CA (SEQ ID NO:9), GAPDH forward: ACCACAGTCC ATGCCATCAC (SEQ ID NO:10) and GAPDH reverse: TCCACCACCC TGTTGCTGTA (SEQ ID NO:11)] and SUPERSCRIPT One-Step RT-PCT with PLATINUM Taq (Invitrogen), RT-PCR was carried out in accordance with the protocol attached to SUPERSCRIPT One-Step RT-PCT with PLATINUM Taq. In brief first strand synthesis was carried out at 50° C. for 30 minutes in a reaction system of 25 μl in total volume. After heating to 94° C. for 2 minutes, each cDNA fragment was amplified in 23 or 20 cycles with each cycle consisting of 30 seconds at 94° C., 30 seconds at 55° C. and 30 seconds at 72° C.

Each reaction solution was electrophoresed in a 1.5% agarose gel and stained with ethidium bromide. FIG. 1 shows the results.

In the case of using the dermal papilla cell (DPC)-derived RNA, a remarkable amplification of the cDNA fragment was observed in the 23-cycle PCR using the WNT-5A-specific primers. In the case of using the hair follicle cell (HFC)-derived RNA, no amplified product was observed under the same conditions.

Measurement of Activity of Decreasing WNT-5A mRNA Amount:

Human dermal papilla cells, which were purchased from Toyobo, were cultured in MEM (Invitrogen) containing 12% FBS.

The dermal papilla cells in passage 5 were sowed in a 12-well plate to give a density of 1.6×10⁵ cells/well and cultured overnight. Then, the medium was replaced by a medium to which no compound was added or a medium containing Compound 1, 2, 3, 4, 5, 7, 9 or 24 and the culture was continued for additional 24 hours. After the completion of the culture, each medium was removed and the cells were washed with PBS(−). Ther

tal RNAs were extracted by using TRIzol reagent (Invitrogen). Using 50 ng of the total RNAs, 0.4 μM of primers specific to WNT-5A or GAPDH [WNT-5A forward; AATGTCTTCC AAGTTCTTCC TAGTGGC (SEQ ID NO:8), WNT-5A reverse: GATGTCGGAA TTGATACTGG CA (SEQ ID NO:9), GAPDH forward: ACCACAGTCC ATGCCATCAC (SEQ ID NO:10) and GAPDH reverse; TCCACCACCC TGTTGCTGTA (SEQ ID NO:11)] and SUPERSCRIPT One-Step RT-PCT with PLATINUM Taq (Invitrogen), RT-PCR was carried out in accordance with the protocol attached to SUPERSCRIPT One-Step RT-PCT with PLATINUM Taq. In brief, first strand synthesis was carried out at 50° C. for 30 minutes in a reaction system of 25 μl in total volume. After heating to 94° C. for 2 minutes, the cDNA fragment of WNT-5A or GAPDH was amplified in 23 or 20 cycles with each cycle consisting of 30 seconds at 94° C., 30 seconds at 55° C. and 30 seconds at 72° C.

Each reaction solution was electrophoresed in a 1.5% agarose gel and stained with ethidium bromide. FIG. 2 shows the results.

In the 23-cycle PCR using the WNT-5A-specific primers, the amplified WNT-5A cDNA fragments was remarkably decreased in the cultures with the compounds, compared with the culture using the medium to which no compound was added.

In the 20-cycle PCR using the GAPDH-specific primers, on the other hand, no change was observed in the amount of amplified cDNA fragment regardless of the presence or absence of the compounds.

Dermal Papilla Cell Growth Promotion Activity Test:

Human dermal papilla cells, which were purchased from Toyobo, were cultured in MEM (Invitrogen) containing 12% FBS.

The dermal papilla cells in passage 5 were sowed in a 96-well plate for spheroid culture to give a density of 1.5×10⁴ cells/well and cultured overnight. Then, the medium was replaced by a medium to which no compound was added or a medium containing Compound 1, 2, 3, 4, 5, 7, 9 or 24 and the culture was continued for additional 72 hours. After the completion of the culture, cells were counted by using Cell Counting Kit (Wako Pure Chemicals). Five hours before the completion of the culture, WST-1 reagent at 1/10 amount per medium was added to each medium and then the optical density (0.1). 450 nm/620 nm) of the medium was measured at the completion of the culture, A positive correlation was observed between the cell number and optical density within the range of 0.25 to 4×10⁴ cells/well.

As a result, it is clarified that a compound having an activity of decreasing WNT-5A mRNA amount has an activity of promoting the growth of dermal papilla cells (FIG. 3). In this figure, each numerical value means an average of 6 wells (control group) or 3 wells (test groups). To compare the control group to the test groups, Student's t-test was employed:

-   -   *:P<0.05, **:P<0.01, ***:P<0.001.

The above-described Test Examples indicates that WNT-5A is expressed in human dermal papilla cells, the amount of WNT-5A mRNA in dermal papilla cells is decreased by the compound according to the present invention, and a compound having an activity of decreasing WNT-5A mRNA amount has an activity of promoting the growth of dermal papilla cells.

Activity of Compounds (Table 2) of Decreasing WNT-5A mRNA Amount (Quantification of mRNA by QuantiGene Method)

Human dermal papilla cells, which were purchased from Toyobo, were cultured in MEM (Invitrogen) containing 12% FBS.

The dermal papilla cells in passage 5 were sowed in a 96-well plate to give a density of 1×10⁴ cells/well and cultured overnight. Then, the medium was replaced by a medium to which no compound was added or a medium containing the compounds and the culture was continued for additional 24 hours. After the completion of the culture, WNT-5A or GAPDH mRNA amount was measured by using QuantiGene High Volume Kit (Bayer Medical) by the branched DNA (bDNA) signal amplification method (Drug Metabolism and Disposition, 28(5), 608-616 (2000)). In accordance with the protocol attached to QuantiGene High Volume Kit, cells were lysed by using Lysis Mixture and the lysis solution was added to capture plate. Next, a set of probes specific to WNT-5A or GPDH was added and allowed to react at 53° C. for 20 hours. After washing the plate by using 0.1×SSC containing 0.03% lauryl sulfate, an amplification probe comprising bDNA was added and allowed to react at 46° C. for 1 hour. After washing the plate, a labeling probe labeled with alkaline phosphatase was added and allowed to react at 46° C. for 1 hour. After washing the plate, a substrate Lumi-Phos Plus was added and allowed to react at 46° C. for 30 minutes. Then, the luminescence was measured by using WALLAC 1420ARVO_(sx).

The WNT-5A-specific probe set was designed based on the sequence of the coding region of human WNT-5A mRNA. As capture extenders (CEs), 10 probes (SEQ ID NOs:12 to 21) were used; as label extenders (LEs), 31 probes (SEQ ID NOs:22 to 52) were employed; and as blockers, 9 probes (SEQ ID NOs:53 to 60) were employed.

As GAPDH-specific probe set, use was made of bDNA probe set for human GAPDH (XenoTech LLC, B0960).

The amounts of WNT-5A and GAPDH mRNAs are expressed in relative values (%) to the control case of adding of no compound and the concentration of a compound at which the mRNA amount is halved (IC₅₀) is calculated as an index of WNT-5A mRNA decreasing activity of the corresponding compound.

Table 3 shows the effects of the compounds on the WNT-5A and GDPH mRNA amounts. Bach numerical value in the table shows the average of 2 wells. These compounds decreased the WNT-5A mRNA amount in dermal papilla cells. The IC₅₀ value of the most active compound was 0.12 μM. At the IC₅₀ concentration of each compound for WNT-5A mRNA suppression, no decrease was observed in the GAPDH mRNA amount measured at the same time.

TEST EXAMPLE 6

Decrease in WNT-5A mRNA in Monkey Skin Organ Culture

The dorsal skin of a Cynomolgus monkey (Macaca fascicularis) (male, 6 years old) was collected and divided into pieces (5 mm×8 mm) under a stereoscopic microscope. Then each skin tissue piece was cultured in William's Medium E (Invitrogen) to which no compound was added or Compound 7 or Compound 3 was added and which contained 10 μg/ml insulin (Sigma) and 10 ng/ml hydrocortisone (Kurabo).

On the 11th day of the culturing, hair follicles were separated from each skin tissue piece and total RNAs were extracted by using TRIzol reagent (Invitrogen). Using 200 ng portions of the total RNAs, 0.4 μM portions of primers specific to WNT-5A or glyceraldehyde3-phosphate dehydrogenase (GAPDH) [WNT-5A sense: AATGTCTTCC AAGTTCTTCC TAGTGGC (SEQ ID NO-8), WNT-5A antisense: GATGTCGGAA TTGATACTGG CA (SEQ ID NO:9), GAPDH sense: ACCACAGTCC ATGCCATCAC (SEQ ID NO:10) and GAPDH antisense: TCCACCACCC TGTTGCTGTA (SEQ ID NO:11)] and SUPERSCRIPT One-Step RT-PCT with PLATINUM Taq (Invitrogen), RT-PCR was cared out in accordance with the protocol attached to SUPERSCRIPT One-Step RT-PCT with PLATINUM Taq. In brief, first strand synthesis was carried out at 50° C. for 30 minutes in a reaction system of 25 μl in total volume in accordance with the protocol attached to SUPERSCRIPT One-Step RT-PCT with PLATINUM Taq. After heating to 94° C. for 2 minutes, the WNT-5A or GPDH cDNA fragment was amplified in 40 or 30 cycles with each cycle consisting of 30 seconds at 94° C., 30 seconds at 55° C. and 30 seconds at 72° C.

Each reaction solution was electrophoresed in a 1.5% agarose gel and stained with Cyber Green (Takara). FIG. 4 shows the results.

In the 40-cycle PCR using the WNT-5A-specific primers, the amplified WNT-5A cDNA fragment was remarkably decreased in the culture with the addition of Compound 7 or Compound 3, compared with the culture to which no compound was added.

In the 30-cycle PCR using the GAPDH-specific primers, on the other band, no change was observed in the amount of amplified cDNA fragment regardless of the presence or absence of the compounds.

TEST EXAMPLE 7

Increase in Proliferating Cell Nuclear Antigen (PCNA)-Positive Cells in Monkey Skin Organ Culture:

The dorsal skin of a Cynomolgus monkey (Macaca fascicularis) (male, 6 years old) was collected and divided into pieces (5 mm×8 mm) under a stereoscopic microscope. Then each skin tissue piece was cultured in William's Medium E (Invitrogen) to which no compound was added or Compound 7 or Compound 3 was added and which contained 10 μg/ml of insulin (Sigma) and 10 ng/ml of hydrocortisone (Kurabo).

On the 30th day of the culturing, the skin tissue pieces were each fixed by using 10% neutralized Formalin at room temperature. A section embedded in paraffin was prepared. After adding 1% BSA-containing PBS, it allowed to stand at room temperature for 30 minutes and then boiled in a 0.1 M citrate buffer solution. Then it was reacted with anti-PCNA antibody (Dako Japan, diluted 200-fold) at 4° C. overnight and then reacted with biotinylated antimouse IgG antibody. Further, it was reacted with ABC standard kit (vector) and subjected to color development using AEC substance (Sigma).

As a result, a positive reaction was observed in cells in hair follicles and the epidermal basal layer. In follicles, remarkable increases in the PCNA-positive cell count are observed in dermal papillae and dermal sheath both in the telogen and anagen hair follicles (FIG. 5).

TEST EXAMPLE 8

Enlargement in Hair Bulb Diameter in Monkey Skin Organ Culture:

The dorsal skin of a Cynomolgus monkey (Macaca fascicularis) (male, 6 years old) was collected and divided into pieces (5 mm×8 mm) under a stereoscopic microscope. Then each skin tissue piece was cultured in William's Medium E (Invitrogen) to which no compound was added or Compound 7 or Compound 3 was added and which contained 10 μg/ml of insulin (Sigma) and 10 ng/ml of hydrocortisone (Kurabo).

On the 30th day of the culturing, all follicles contained in each skin tissue piece were separated and the diameter of bulbs was measured under a stereoscopic microscope.

FIGS. 6 and 7 show the results. In these figures, each numerical value means mean±S.E. of bulb diameters of all follicles contained in each skin tissue piece. To compare the control group with the test groups, Student's t-test was employed:

-   -   *:P<0.05.

These figures also present histograms showing the bulb diameter distribution. All follicles contained in each skin tissue piece are divided into bulb diameter groups as indicated in the figures and follicle count in each group is expressed in the relative value (%) to the total follicle count separated from the tissue piece. FIG. 6 shows the effect achieved after culturing in the presence of Compound 7. After culturing in the presence of Compound 7 for 30 days, the average bulb diameter of the follicles contained in the skin piece was significantly higher than that of the control group to which no compound was added. As shown by the distribution, the control group to which no compound was added showed the largest follicle count in the group of diameter of 140 μm or longer but shorter than 170 μm, whereas the group to which Compound 7 was added showed the largest follicle count in the group of diameter of 170 μm or longer but shorter than 200 μm. The ratio of follicles of 170 μm or longer in bulb diameter in the group to which no compound was added was 57.6%, whereas the ratio in the group to which Compound 7 was elevated to 82.4%.

On the other hand, FIG. 7 shows the effect achieved after culturing in the presence of Compound 3. Similar to the case of Compound 7, after culturing in the presence of Compound 3 for 30 days, the average bulb diameter of the follicles contained in the skin piece was significantly higher than that of the control group to which no compound was added. As shown by the distribution, the control group to which no compound was added showed the largest follicle count in the group of diameter of 140 μm or longer but shorter than 170 μm, whereas the group to which Compound 3 was added showed the largest follicle count in the group of diameter of 200 μm or longer but shorter than 230 μm. The ratio of follicles of 170 μm or longer in bulb diameter in the group to which no compound was added was 55.8%, whereas the ratio in the group to which Compound 7 was elevated to 74.5%.

TEST EXAMPLE 9

Hair Growth te

Stumptailed Macaque:

To the forehead of a stumptailed macaque (Macaca arctoides) (male, 14 years old) suffering from alopecia, 1 mL of a lotion containing 0.3% Compound 7 was applied once a day 5 times per week for 6 months. Before the initiation of the application, the alopecia site in the forehead was marked by tattoo. The skin part including the tattoo was photographed before the initiation of the application and after applying for 6 months.

FIG. 8 provides enlarged photos of the skin before and after application of the lotion containing Compound 7 for 6 months. Before the application, many thin vellus hairs were observed. In the same site after applying for 6 months in contrast, vellus hairs decreased and thick terminal hairs increased. That is, it is recognized that the alopecia in the forehead of the stumptailed macaque was clearly ameliorated by applying the lotion containing Compound 7 for 6 months.

The results of the above Test Examples indicate that WNT-5A is expressed in human dermal papilla cells, the amount of WNT-5A mRNA in human dermal papilla cells is decreased by the compound according to the present invention, and a compound having an activity of decreasing WNT-5A mRNA amount has an activity of promoting the growth of dermal papilla cells.

It is also indicated that the compound according to the present invention causes a decrease in the WNT-5A mRNA amount in monkey skin organ culture too, the compound causes a remarkable increase in the PCNA-staining positive proliferative cells both in the telogen and anagen hair follicles, and the compound enlarges the bulb size of follicles.

It is furthermore indicated that the compound according to the present invention has an affect of ameliorating alopecia of a stumptailed macaque which is a model animal of male pattern alopecia.

That is to say, a compound promoting the growth of dermal papilla cells would enhance the cell growing ability, which has been lowered in the dermal papillae in follicles in a part with alopecia, and thus contributes to the formation of well-developed dermal papilla tissues, thereby promoting hair growth.
